Christian ethics is not only about principles and theories — it is about action. This lesson examines how Christians have translated moral convictions into practical engagement with the world, focusing on two towering figures: Dietrich Bonhoeffer and Martin Luther King Jr. Both paid the ultimate price for their commitment to justice, and both continue to shape Christian thinking about the relationship between faith and political action.
Dietrich Bonhoeffer (1906–1945) was born into a privileged, cultured German family. He completed his doctorate in theology at the age of twenty-one and studied at Union Theological Seminary in New York, where he was deeply influenced by African-American church life in Harlem. He returned to Germany as the Nazi regime was consolidating power.
| Date | Event |
|---|---|
| 1933 | The Nazis came to power. Bonhoeffer immediately opposed the Aryan paragraph, which sought to exclude Christians of Jewish descent from the Church |
| 1934 | Bonhoeffer was involved in the founding of the Confessing Church (Bekennende Kirche), which rejected the Nazi-controlled Deutsche Christen (German Christians) |
| 1935–1937 | Bonhoeffer ran an illegal seminary at Finkenwalde, training pastors for the Confessing Church. This experience shaped The Cost of Discipleship (1937) and Life Together (1939) |
| 1939 | Bonhoeffer travelled to the United States but returned to Germany after only a few weeks, writing: "I shall have no right to participate in the reconstruction of Christian life in Germany after the war if I do not share the trials of this time with my people" |
| 1940–1943 | Bonhoeffer joined the Abwehr (military intelligence) as a double agent, using his ecumenical contacts to communicate with the Allied powers. He was involved in the conspiracy to assassinate Hitler |
| April 1943 | Arrested by the Gestapo and imprisoned |
| 9 April 1945 | Executed at Flossenbürg concentration camp, just weeks before Germany's surrender |
In his Letters and Papers from Prison (published posthumously in 1951), Bonhoeffer wrestled with the question of what Christianity means in a world that has "come of age" — a world that no longer needs God as an explanation for natural phenomena.
Key Definition: Religionless Christianity is Bonhoeffer's provocative idea that Christianity must move beyond "religion" — understood as a separate, private, otherworldly sphere — and engage with the whole of life. God is not a "God of the gaps" invoked to explain what science cannot, but the God who is present in the centre of life, in strength and suffering alike.
Bonhoeffer asked: "Who is Christ for us today?" He argued that Christ is not found in religious rituals and metaphysical systems but in the community of believers living for others. The Church must be a "Church for others" — not an institution concerned with its own survival but a community that exists to serve the world.
Bonhoeffer's most agonising ethical decision was his involvement in the plot to kill Hitler. As a pacifist by conviction (influenced by the Sermon on the Mount and by his meeting with Gandhi's associates in London), he found this decision excruciating. He came to believe that:
| Aspect | Bonhoeffer's Position |
|---|---|
| Duty to the state | The state has a legitimate role, but when it systematically oppresses people, Christians have a duty to resist — by direct political action if necessary |
| Individual conscience | Conscience is important but can be manipulated; the Christian's ultimate loyalty is to Christ, not to conscience or the state |
| Use of violence | Bonhoeffer was deeply reluctant to endorse violence but concluded that in the specific situation of Nazi Germany, participation in the assassination plot was the responsible choice |
In Life Together (1939), based on his experience at Finkenwalde, Bonhoeffer described the nature of Christian community.
Key Definition: Bonhoeffer's concept of Stellvertretung (vicarious representative action) means that Christians are called to act on behalf of others, standing in their place and bearing their burdens — just as Christ stood in humanity's place on the cross.
